         9 . The cartridge assembly of  claim 8 , additionally comprising a manifold for holding and distributing aerosolized nicotine, the manifold positioned above the top wall of the reservoir, the manifold having an open top end and two open bottom ends, and at least one interior channel connecting the open top end with the open bottom ends, wherein the open bottom ends of the manifold are secured onto the open top ends of the conduits and are in fluid communication with the conduits. 
     
     
         10 . The cartridge assembly of  claim 9 , further comprising a mouthpiece positioned above the manifold having an outlet in fluid communication with the at least one interior channel of the manifold, the mouthpiece configured for delivering aerosolized nicotine into the mouth of a user. 
     
     
         11 . The cartridge assembly of  claim 1 , wherein the composition in reservoir comprises:
 a. nicotine or a salt thereof in an amount of from about 2 to about 6% w/w,   b. propylene glycol in an amount of 60% w/w, and   c. water in an amount of 40% w/w.   
     
     
         12 . The cartridge assembly of  claim 1 , further comprising an anti-counterfeit element mounted to the outer surface of the body assembly, the anti-counterfeit element configured to enable use of the cartridge assembly in the electronic nicotine delivery device. 
     
     
         13 . The cartridge assembly of  claim 12 , wherein the anti-counterfeit element comprises a plurality of electrically conducting pads mounted on a substrate attached to the body assembly of the cartridge assembly, the plurality of electrically conducting pads configured to make electrical contact with corresponding electrical contact elements on a circuit board within a housing of the medical electronic nicotine delivery device, the plurality of electrically conducting pads being arranged in a predetermined pattern having predetermined electrical characteristics. 
     
     
         14 . The cartridge assembly of  claim 1 , further comprising an anti-reuse element mounted to the outer surface of the body assembly, the anti-reuse element configured to preclude reuse of the cartridge assembly once removed from the medical electronic nicotine delivery device. 
     
     
         15 . The cartridge assembly of  claim 14 , wherein the anti-reuse element comprises one or more springs configured to make electrical contact with a corresponding electrical pad mounted on circuit board within a housing of the medical electronic nicotine delivery device, the one or more springs being configured to be disrupted upon removal of the cartridge assembly from the housing. 
     
     
         16 . A kit comprising at least one nicotine containing cartridge assembly of  claim 1  and the medical electronic nicotine delivery device. 
     
     
         17 . The kit of  claim 16  comprising at least two cartridge assemblies. 
     
     
         18 . A medical electronic nicotine delivery system comprising the cartridge assembly of  claim 1  and the medical electronic nicotine delivery device. 
     
     
         19 . The medical electronic nicotine delivery system of  claim 18 , wherein the medical electronic delivery device comprises a housing, an electrical module, a power supply, a heater, and a vaporization chamber.
